Abstract :
CSI is a STAP technology like displaced phase center antenna(DPCA).Its virtue is that it couldn´t be confined by DPCA conditions. This paper briefly analyses the principle and shortage of conventional CSI firstly. Then making dual-channel GMTI as an example, puts forward an improved CSI processing method. Lastly, we compare channel-cancellation result of simulated date and real dual-channel echo data, The results proved this improved CSI method is reliable and effectual.
